For example, the above Tax Foundation table shows that the top 10 percent in income of taxpayers, those making more than $113,799 per year, paid 70 percent of all individual income taxes. The bottom 50 percent of taxpayers paid only 2.7 percent of US income taxes.

There are about 230 million people in the US over 25 years old and about 190 million between the ages of 25 and 65 years old. In 2008, only 140 million individual returns with positive income were filed, which is pretty close to the number of working individuals.

In 2008, there were about 213 million eligible US voters. Less than 7 percent of eligible voters are paying 70 percent of the US income tax. 33 percent of eligible voters are paying 97 percent of US income taxes.
